Failure to do whatever is reasonably possible to help Ukraine maintain her sovereignty and security would also put the United States and the UK in violation of this agreement.
The Budapest Memorandum on Security Assurances basically guaranteed Ukraine's sovereignty and security in exchange for surrendering her nuclear weapons after the fall of the Soviet Union. As a result, Ukraine gave up the world's third largest nuclear weapons stockpile between 1994 and 1996.
